1, the head 52 of the piston 51 on the compression stroke side is pressed against the rotating three-dimensional cam 55 via the roller 56 (left side in Figure 5) due to the compression reaction force, and maintains the most stable posture. try to.
At this time, the roller 56 on the suction stroke side located on the right side of FIG.
When the roller 56 is tilted toward the three-dimensional cam 55 as shown by the chain line in FIG.
When the roller 56 tilts to the opposite side with the force of this repulsion, this time the roller 56
The lower edge of the roller 56 is repelled by the three-dimensional cam 55 and tilted, and this tilting operation is repeated in a short period of time, causing the roller 56 to chattering. This chattering also occurs in a direction perpendicular to the paper plane of FIG. 5, and as a result, both ends of the roller 56 intermittently bite against the cam surface of the three-dimensional cam 55 and the inner peripheral surface of the mooring recess 52a. There were problems in that hitting noise was generated, the cam surface and the roller 56 were damaged, and the mooring recess 52a made of a material with a lower hardness than the roller 56 was worn out at an early stage.
